I would like to announce the release of MediaWiki 1.24.2, 1.23.9 and 1.19.24. These releases fix 10 security issues, in addition to other bug fixes. Download links are given at the end of this email.
== Security fixes ==
* iSEC Partners discovered a way to circumvent the SVG MIME blacklist for embedded resources (iSEC-WMF1214-11). This allowed an attacker to embed JavaScript in the SVG. The issue was additionally identified by Mario Heiderich / Cure53. MIME types are now whitelisted. https://phabricator.wikimedia.org/T85850
* MediaWiki user Bawolff pointed out that the SVG filter to prevent injecting JavaScript using animate elements was incorrect. https://phabricator.wikimedia.org/T86711
* MediaWiki user Bawolff reported a stored XSS vulnerability due to the way attributes were expanded in MediaWiki's Html class, in combination with LanguageConverter substitutions. https://phabricator.wikimedia.org/T73394
* Internal review discovered that MediaWiki's SVG filtering could be bypassed with entity encoding under the Zend interpreter. This could be used to inject JavaScript. This issue was also discovered by Mario Gomes from Beyond Security. https://phabricator.wikimedia.org/T88310
* iSEC Partners discovered a XSS vulnerability in the way api errors were reflected when running under HHVM versions before 3.6.1 (iSEC-WMF1214-8). MediaWiki now detects and mitigates this issue on older versions of HHVM. https://phabricator.wikimedia.org/T85851
* Internal review and iSEC Partners discovered (iSEC-WMF1214-1) that MediaWiki versions using PBKDF2 for password hashing (the default since 1.24) are vulnerable to DoS attacks using extremely long passwords. https://phabricator.wikimedia.org/T64685
* iSEC Partners discovered that MediaWiki's SVG and XMP parsing, running under HHVM, was susceptible to "Billion Laughs" DoS attacks (iSEC-WMF1214-13). https://phabricator.wikimedia.org/T85848
* Internal review found that MediaWiki is vulnerable to "Quadratic Blowup" DoS attacks, under both HHVM and Zend PHP. https://phabricator.wikimedia.org/T71210
* iSEC Partners discovered a way to bypass the style filtering for SVG files (iSEC-WMF1214-3). This could violate the anonymity of users viewing the SVG. https://phabricator.wikimedia.org/T85349
* iSEC Partners reported that the MediaWiki feature allowing a user to preview another user's custom JavaScript could be abused for privilege escalation (iSEC-WMF1214-10). This feature has been removed. https://phabricator.wikimedia.org/T85855
Additionally, the following extensions have been updated to fix security issues:
* Extension:Scribunto - MediaWiki user Jackmcbarn discovered that function names were not sanitized in Lua error backtraces, which could lead to XSS. https://phabricator.wikimedia.org/T85113
* Extension:CheckUser - iSEC Partners discovered that the CheckUser extension did not prevent CSRF attacks on the form allowing checkusers to look up sensitive information about other users (iSEC-WMF1214-6). Since the use of CheckUser is logged, the CSRF could be abused to defame a trusted user or flood the logs with noise. https://phabricator.wikimedia.org/T85858
== Bug fixes ==
=== 1.24 ===
* Fix case of SpecialAllPages/SpecialAllMessages in SpecialPageFactory to fix loading these special pages when $wgAutoloadAttemptLowercase is false. * (bug T76254) Fix deleting of pages with PostgreSQL. Requires a schema change and running update.php to fix.
== 1.23 & 1.24 ==
* (bug T70087) Fix Special:ActiveUsers page for installations using PostgreSQL.

Chris,
There might be something wrong with the mediawiki-1.23.9.patch file. I've been using the patches to do point-release upgrades for quite a while, and this is the first time I've seen something like this:

So it appears tests have made their return to releases... in a security release.
I did also raise this on IRC but I was told that not having tests in the tarball was wrong. My IRC client conveniently decided to stop listening to my keyboard just as I was about to reply. But as someone else has raised this issue, we might as well have the 'tests in tarball' conversation again, for the third or fourth time in recent history...
